Description

Technical Field

[0001] This utility model relates to the technical field of steel structure operating platforms, and in particular to a movable prefabricated steel structure operating platform. Background Technology

[0002] A steel structure operating platform is a temporary or permanent working platform built with steel as the main component. It is widely used in construction, industrial production, equipment maintenance and other scenarios. It is usually made of steel sections (such as I-beams and channel steel) welded or bolted together to form a frame, and the surface is covered with patterned steel plates or gratings to form a working surface. It is assembled and combined, and some are equipped with safety facilities such as guardrails and ladders to ensure the safety of personnel.

[0003] In daily work, it has been found that the support parts of some existing prefabricated steel structure operating platforms are usually equipped with casters. The casters are used to move the prefabricated steel structure operating platform. However, after the casters are locked, the overall weight of the platform is supported by multiple casters. Long-term load-bearing can easily cause structural wear or damage to the casters, affecting their service life. Moreover, even after the casters are locked, instability can still occur, causing slight displacement or shaking of the platform. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the existing technology where long-term load-bearing easily leads to structural wear or damage to the casters, affecting their service life, and the casters are still unstable even after being locked, causing slight displacement or shaking of the platform. Therefore, a movable prefabricated steel structure operating platform is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a movable prefabricated steel structure operating platform, comprising multiple steel structure supports, a steel structure frame installed above the multiple steel structure supports, steel plates provided on the steel structure frame, casters installed on the surface of the steel structure supports, and auxiliary devices provided on the steel structure supports; The auxiliary device includes a movable seat slidably connected to the inner wall of a steel structure support. Two rotating sleeves are rotatably connected to the surface of the movable seat, and support legs are fixedly connected to the surface of each rotating sleeve. A storage assembly is provided between the steel structure support and the rotating sleeves, used to rotate and store the support legs after the movable seat is reset. An unfolding assembly is provided between the movable seat and the rotating sleeves, used to unfold the support legs for support during use. A positioning assembly is provided between the movable seat and the steel structure support, used to position the movable seat. Through these components, during use, the movable seat can be pushed downwards, causing the support legs to move downwards. Subsequently, the unfolding assembly unfolds the support legs, placing them in a supporting state. Further pushing the movable seat brings the support legs into contact with the ground, and then the positioning assembly positions the movable seat, thus achieving auxiliary support, reducing the stress on the casters, and improving the overall stability of the support.

[0006] Preferably, the storage component includes multiple sets of racks fixed to the surface of the steel structure support, and two gears are fixedly connected to the surface of the rotating sleeve. Through the above components, when the moving seat moves upward to reset, after moving to a certain position, the racks mesh with the gears, and then drive the gears and the rotating sleeve to rotate, so as to store the unfolded support legs.

[0007] Preferably, the unfolding assembly includes two fixed rings fixed to the surface of the movable seat, and an unfolding spring is sleeved on the movable seat. The two ends of the unfolding spring are fixedly connected to the surfaces of the fixed rings and the rotating sleeve, respectively. Through the above components, the elastic force of the unfolding spring can drive the rotating sleeve and the support leg to unfold, so as to facilitate the support operation.

[0008] Preferably, a positioning protrusion is fixedly connected to the inner wall of the rotating sleeve, and a positioning groove is opened on the surface of the movable seat. The positioning protrusion is inserted into the inner wall of the positioning groove. Through the above components, during the rotation and unfolding process of the unfolding spring driving the rotating sleeve and the support leg, when unfolded to the support state, the positioning protrusion can abut against the inner wall of the positioning groove to position the unfolded state of the support leg and ensure the stable support effect of the support leg.

[0009] Preferably, the positioning component includes two positioning rods slidably connected to the inner wall of the movable seat. Two positioning holes are opened on both sides of the steel structure bracket. The positioning rods are inserted into the inner walls of the positioning holes. A positioning spring is sleeved on the surface of the positioning rod. The two ends of the positioning spring are fixedly connected to the surface of the positioning rod and the surface of the movable seat, respectively. Through the above components, the positioning spring can drive the positioning rod to be inserted into the positioning holes at different positions, thereby positioning the movable seat at different positions. At the same time, the elasticity of the positioning spring can ensure the stability of the positioning rod after insertion.

[0010] Preferably, the lower surface of the movable seat is fixedly connected with four support columns. Through the above components, when the movable seat drives the support leg to fit into the ground, the support columns on the movable seat also fit into the ground, cooperating with the support leg to provide auxiliary support.

[0011] Preferably, the movable seat is composed of two U-shaped blocks and two cylindrical rods fixedly connected to the inner sides of the two U-shaped blocks.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting an auxiliary device, the supporting leg is moved downward by the movable seat, and the unfolding component can drive the supporting leg to unfold stably. After the movable seat drives the supporting leg to fit against the ground, it can be positioned by the positioning component. The supporting leg, together with the universal wheel, achieves a multi-point support effect, which disperses the stress points of the overall weight, reduces the load on the universal wheel, reduces the phenomenon of damage to the universal wheel, and at the same time greatly increases the contact area with the ground, improving the stability during operation.

[0013] In this invention, when the movable seat moves up and down, the rack and gear in the storage component come into contact, which can drive the rotating sleeve and the support leg to rotate and be stored, so that the support leg fits into the steel structure bracket without taking up extra space.

[0016] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a movable prefabricated steel structure operating platform, including multiple steel structure supports 1, a steel structure frame 2 installed above the multiple steel structure supports 1, a steel plate 3 provided on the steel structure frame 2, casters 4 installed on the surface of the steel structure supports 1, and auxiliary devices 5 provided on the steel structure supports 1.

[0017] Specifically, the auxiliary device 5 includes a movable seat 51 that is slidably connected to the inner wall of the steel structure support 1. Two rotating sleeves 57 are rotatably connected to the surface of the movable seat 51. Support legs 53 are fixedly connected to the surface of the rotating sleeves 57. A storage component is provided between the steel structure support 1 and the rotating sleeves 57, which is used to drive the support legs 53 to rotate and store after the movable seat 51 is reset. An unfolding component is provided between the movable seat 51 and the rotating sleeves 57, which is used to unfold the support legs 53 for support during use. A positioning component 52 is provided between the movable seat 51 and the steel structure support 1, which is used to position the movable seat 51. The movable seat 51 is composed of two U-shaped blocks and two cylindrical rods fixedly connected to the inner side of the two U-shaped blocks.

[0018] In this implementation scheme: During use, the movable seat 51 can be pushed downwards, which in turn moves the support leg 53 downwards. Then, the unfolding component unfolds the support leg 53, putting it in a supporting state. The movable seat 51 is then pushed further to bring the support leg 53 into contact with the ground. Subsequently, the movable seat 51 is positioned by the positioning component 52, thus achieving auxiliary support, reducing the force on the caster wheel 4, and improving the overall stability of the support.

[0019] Specifically, the storage component includes multiple sets of racks 55 fixed to the surface of the steel structure bracket 1, and two gears 56 fixedly connected to the surface of the rotating sleeve 57.

[0020] In this implementation scheme: when the movable seat 51 moves upward to reset, after moving to a certain position, the rack 55 meshes with the gear 56, which then drives the gear 56 and the rotating sleeve 57 to rotate, and the unfolded support leg 53 is stored.

[0021] Specifically, the unfolding assembly includes two fixing rings 58 fixed on the surface of the movable base 51. An unfolding spring 59 is sleeved on the movable base 51. The two ends of the unfolding spring 59 are fixedly connected to the surfaces of the fixing rings 58 and the rotating sleeve 57, respectively. A positioning protrusion 511 is fixedly connected to the inner wall of the rotating sleeve 57. A positioning groove 510 is opened on the surface of the movable base 51. The positioning protrusion 511 is inserted into the inner wall of the positioning groove 510.

[0022] In this implementation scheme: the elastic force of the unfolding spring 59 can drive the rotating sleeve 57 and the support leg 53 to unfold, so as to facilitate the support operation. During the process of the unfolding spring 59 driving the rotating sleeve 57 and the support leg 53 to rotate and unfold, when unfolded to the support state, the positioning protrusion 511 can abut against the inner wall of the positioning groove 510 to position the support leg 53 in the unfolded state, so as to ensure the stable support effect of the support leg 53.

[0023] Specifically, the positioning component 52 includes two positioning rods 521 that are slidably connected to the inner wall of the movable seat 51. Two positioning holes 523 are opened on both sides of the steel structure bracket 1. The positioning rods 521 are inserted into the inner wall of the positioning holes 523. A positioning spring 522 is sleeved on the surface of the positioning rods 521. The two ends of the positioning spring 522 are fixedly connected to the surfaces of the positioning rods 521 and the movable seat 51, respectively.

[0024] In this implementation scheme: when the positioning spring 522 drives the positioning rod 521 to be inserted into the positioning hole 523 at different positions, the moving seat 51 at different positions can be positioned respectively. At the same time, the elasticity of the positioning spring 522 can ensure the stability of the positioning rod 521 after it is inserted.

[0025] Specifically, the lower surface of the movable base 51 is fixedly connected with support columns 54, and there are four support columns 54.

[0026] In this implementation plan: when the movable seat 51 drives the support leg 53 to fit into the ground, the support column 54 on the movable seat 51 also fits into the ground, and works with the support leg 53 to provide auxiliary support.

[0027] Working principle: During use, the casters 4 under the steel structure support 1 drive the entire platform to move. After the position is reached, the positioning rod 521 can be pulled, and the positioning spring 522 is stressed. The positioning rod 521 moves out of the positioning hole 523 on the surface of the steel structure support 1, losing its restraint on the moving seat 51. Then, the moving seat 51 is pushed downward. When the moving seat 51 moves, the rack 55 and the gear 56 can drive the rotating sleeve 57 and the support leg 53 to rotate and unfold. At the same time, the unfolding spring 59 can ensure the stability of the unfolded support leg 53. After the rotating sleeve 57 rotates to a certain position, the positioning protrusion 511 on the surface of the rotating sleeve 57 abuts against the inner wall of the positioning groove 510. This limits the unfolding angle of the rotating sleeve 57 and the support leg 53. After the movable seat 51 moves to the appropriate position, the support leg 53, together with the support column 54, can fit against the ground. The positioning rod 521 is released, and the positioning spring 522 drives the positioning rod 521 to be inserted into the corresponding positioning hole 523 on the surface of the steel structure bracket 1. At this time, the stability of the whole is improved when it is placed, and the weight of the caster wheel 4 is also shared, which improves the overall service life. When the movable seat 51 moves upward and resets, the rack 55, together with the gear 56, can drive the unfolded rotating sleeve 57 and the support leg 53 to rotate, so that it is in the storage state. Then, the positioning rod 521 and the positioning spring 522 are used to position the movable seat 51.
